Introduction

This standard is one of the series of WLAN standards and its evolution is after IEEE 802.11n.
This 802.11ac technology is developed to provide data rate in Gbps for wireless devices mainly
for WLAN applications.
In the previous versions of 802.11 series of standards were designed for single user operation.
In 802.11ac multi user concept was introduced with multiuser MIMO feature.
Beamforming has been added to cover more region and specific region with the focused beam concept.
